Anyone know how much they are? Are nissan dealerships the only place they can be bought?

Is this rear one you speak of the one in the catalytic converter?

How many O2 sensors does a Sentra have altogether?

 

[200SXSE]

Yes that is the sensor I speak of. Mine has been out for a while. I was also wondering how much it would help when i replace it.

I was told pep boys has em for $15 - $30.
Bosch brand.

Ok..cause thats what brand it is. Thanks.

I don't believe Pep Boys carries the rear O2 sensor. Make sure you look at the sensor before you buy their universal one as the rear sensor is a lot smaller, at least mine is.
